Anthology of Ideas

Does Super Categories work with 2.5.x? Do you currently use this or have you found/recommend alternative to having domain, multiple parked domains, forum, and other shared or independent blogs on your Web sites?

For myself, I have my primary domain and multiple parked domains. I want to have each presented via blog. Some content will share across each, such as support forum, classifieds using a blog, photo gallery via blog, and maybe even selected text posts. Each domain and parked domain will have its own theme and own primary content that will be unique. Your thoughts on how best to approach this?

Thanks,
Matthew
